A camera lens is made of several lenses and those objects could just be a single light artifact that has been distorted into a meaningful shape and then repeatedly reflected between the lens surfaces.and then onto the sensor. The coating on the glass usually eliminates this but under certain conditions it can still happen. You most often see this phenomenon, in some pictures or videos, in the shape of repeated hexagons when the sun is in or near view, which is actually the shape of the camera's aperture. It's a sign that the coating has failed under these conditions or the lenses are dirty or moisture has condensed on them.
